Irrigation plays an important role in melon (Cucumis melo L.) production. The study was conducted to compare the influence of irrigation frequency on growth and yield of melon and to identify the irrigation water use efficiencies of each treatment. The experimental plot was designed in RCBD layout divided into four treatments with three replications. They were Treatment 1 (T1), irrigated by drip irrigation 1 time per day, Treatment 2 (T2) irrigated by drip irrigation 2 times per day, Treatment 3 (T3) irrigated by drip irrigation 3 times per day, and Treatment 4 (T4) irrigated by hand-watering 2 times per day. All treatments were applied with the same amount of irrigation water based on crop water requirement calculation. Statistical analysis was done by ANOVA in SPSS software. The results indicate that T3 significantly affected on vegetative development (plant height and plant diameter), water use efficiency (WUE), dried and wet mass and yield of melon. The highest yields were obtained from T3 of 46.75 tons/ha with WUE of 78.18 kg m-3, while the plant height and plant diameters were 164.33 cm and 10.55 mm and the lowest at the T4 of 29.17 tons/ha with WUE of 51.98 kg m-3, while the plant height and plant diameters were 148.33 cm and 9.63 mm. However, there were no significant differences in water use efficiency between T1, T2 and T4 which are 55.60 kg m-3, 64.10 kg m-3 and 51.98 kg m-3, respectively. Therefore, based on vegetative development, yield and quality of melon, T3 treatment would be the most appropriate irrigation for melon growers in controlled conditions.
